Description

FIELD OF THE INVENTION
• The present invention relates generally to a method, system and media for wireless process control of mobile equipment.
BACKGROUND OF THE INVENTION
• In remote mobile mining operations, a train of mobile mining equipment comprised of one or more pieces of mobile equipment, may work together in mining and processing a mined resource material. Communication between the various large pieces of mining equipment is accomplished through a wired medium. Although wired systems can assist in the control and operation of mobile equipment, they also present many challenges. In general, wired systems are limited in their ability to support process control by the extent and availability of wired connections. In addition, with wired systems, an operator of the mobile equipment is at the mercy of the cabling required, which can reduce mobility, range of operation and range of motion of the mobile equipment. Cabling in a wired system is also susceptible to both physical and environmentally induced damage, including from inadvertent operator and equipment impacts.
• In the context of large mobile mining equipment, wired systems are yet further susceptible to damage and operational and maintenance problems. For instance, large mobile mining equipment can have hundreds or thousands of 110 points, further complicating the cabling requirements. The result is that for a wired system the cabling requirements are often very substantial, with very large numbers of cables connected to the various pieces of mining equipment. In addition, when one wishes to relocate a train of mobile mining equipment, or swap out one of the pieces of mobile mining equipment, a vast array of cables forming part of the wired control system often needs to be disconnected, collected and then laid out and reconnected at the new mining operations site. Given the critical data and instructions that may need to be communicated over the wired system, reconnecting all of the cabling can lead to a tremendous amount of time spent recommissioning the mobile mining equipment to ensure that all cabling has been correctly reconnected.
• There is therefore a need for a method and system of wireless control of mobile equipment that offers enhancements or alternatives to the manner in which mobile equipment, including mobile mining equipment, is controlled and operated remotely.

DETAILED DESCRIPTION
• Referring toFIGS. 1 and 2, there is shown a first embodiment of asystem10 for wireless process control, for use in the mining industry in accordance with one aspect of the present invention. In general terms, thesystem10 comprises at least a firstwireless network36 and a secondwireless network38, which use different radio frequency bands that do not substantially interfere with each other. The firstwireless network36 is used to communicate real-time instructions and data between one or more pieces of mobile equipment to at least one other piece of mobile equipment. The secondwireless network38 is used to concurrently communicate the same or substantially the same real-time instructions and data as are communicated over the firstwireless network36. The concurrent operation of the two wireless networks supports a reliable system for remote monitoring and control of the mobile equipment, while minimizing the risk of an interruption or loss of communication of real-time instructions and data.
• In the first embodiment, thesystem10 includes a mobile mining process train50 (or mobile mining process line) for use in the mobile excavation and mining of a mineable resource material. In operation, the mobilemining process train50 is located proximate an open pit oil sands mine face and comprises a plurality of mobile mining equipment, including amobile shovel22, amobile sizer20, a mobile mining conveyor hopper (or MMCH)18, a mobile mining conveyor (or MMC)16 and amobile slurry facility14, although other types of mobile mining equipment may be used.
• Themobile shovel22 is operative to excavate the mineable resource material from a resource-bearing body, the excavated mineable resource material forming a mined material. In the first embodiment, the mined material comprises a bitumen-bearing formation material excavated from an oil sands deposit, although the mined material may comprise any other form of mineable resource material, including an ore-bearing material excavated from an ore-bearing body. Themobile sizer20 is operative to receive the mined material from themobile shovel22 and to comminute the mined material to a conveyable size. Preferably, themobile sizer20 causes the mined material to have pieces of material that do not exceed a predetermined size. The mobilemining conveyor hopper18 is operative to receive the mined material from themobile sizer20 for transfer at a regulated rate to themobile mining conveyor16. Themobile mining conveyor16 is operative to receive the mined material from the mobilemining conveyor hopper18 and to transport the mined material for processing downstream. Themobile slurry facility14 is operative to receive the mined material from themobile mining conveyor16 and to size and combine it with water for transport to an extraction facility. The mobilemining process train50 may include other pieces of equipment, including, for instance, atransfer conveyor52 that acts as a bridge, receiving the mined material from themobile mining conveyor16 via the receivingend54 and transporting the mined material to themobile slurry facility14. It will be noted that the pieces of mobile mining equipment identified above are illustrative of, but are not meant to limit, the types of mobile mining equipment that may be used in thesystem10. For instance, themobile sizer20 may be any type of mobile comminuting device suitable for mining, including a mobile crusher. Themobile shovel22 may also be any type of mobile excavator suitable for mining, including a mobile loader. In addition to supporting communications with the mobile mining equipment, thesystem10 can also support communications with other sites and other forms of equipment, such as a hydro-transport booster pump house (HTBPH)24 or another type of hydro-transport booster pump, which may be mobile or relocatable.
• Thesystem10 cooperates with aremote plant28 for monitoring the mobilemining process train50 and for sending and receiving data to and from the mobilemining process train50. Communication between theremote plant28 and the mobilemining process train50 may be accomplished directly or indirectly, including, for example, through asubstation26, wherein thesubstation26 communicates over afirst communication medium30 with themobile slurry facility14 and the mobile slurry facility communicates over thefirst communication medium30 with the rest of the mobilemining process train50.
• Thefirst communication medium30 is a wireless medium further comprising at least twowireless connections32 and34 that operate at substantially different radio frequency bands from each other. Thewireless connections32 and34 provide concurrent point-to-point connections between thesubstation26 and the hub of the mobilemining process train50, which in the first embodiment is positioned on themobile slurry facility14. In the first embodiment,wireless connections32 and34 are an IEEE 802.11 g wireless connection and an IEEE 802.11a wireless connection respectively, although other wireless communications standards may be used provided that the two wireless connections use different radio frequency bands that do not substantially interfere with each other.
• In the first embodiment, themobile slurry facility14 serves as a gateway for the mobilemining process train50, sending and receiving data between the mobilemining process train50 andsubstation26. Thesubstation26 serves as a communication interface for theremote plant28 wherein communication between thesubstation26 andremote plant28 occurs over asecond communication medium37, which is, for illustration purposes, a single mode fiber, although other wired or wireless connections may be used for thesecond communication medium37.
• Communication in and between the mobile mining equipment, including themobile slurry facility14, is managed via thefirst wireless network36 and thesecond wireless network38. In the first embodiment, communication between theremote plant28 and the mobile mining equipment of the mobilemining process train50, other than themobile slurry facility14, is facilitated through themobile slurry facility14. The remote plant28 (via the substation26) communicates with themobile slurry facility14 while the other mobile mining equipment, such as themobile mining conveyor16, communicates with themobile slurry facility14 over both thefirst wireless network36 and thesecond wireless network38.
• Thefirst wireless network36 operates using a radio frequency in accordance with the IEEE 802.11 g standard. Thesecond wireless network38 operates using a different radio frequency in accordance with the IEEE 802.11a standard. It will be noted, however, that other wireless communications standards may be used for the first and second wireless networks provided that the two wireless networks use different radio frequency bands that do not substantially interfere with each other.
• Thewireless connections32 and34 provide real-time concurrent wireless connections between themobile slurry facility14 andsubstation26, while thewireless networks36 and38 provide real-time concurrent wireless connections between themobile slurry facility14 and the other pieces of mobile mining equipment in the mobilemining process train50.
• Referring toFIGS. 1,2 and3, the mobile equipment communication and control portion of thesystem10 for each of the pieces of mobile mining equipment of themobile mining train50 is shown in more detail at70. Each of the mobile mining equipment has positioned on it an equipment data collector andcontroller80 that collects a set of status and operational data from the corresponding piece of mobile mining equipment, and is operative to control at least one feature of the corresponding piece of mobile mining equipment. Instances of the equipment data collector andcontroller80 shown inFIG. 1 include those referenced at40,41,42,43,44,45 and46.
• Each equipment data collector andcontroller80 includes a programmable logic controller (PLC) programmed to support to the operation of the respective equipment data collector and controller. Each of the pieces of mobile mining equipment also has positioned on it, either as part of or in communication with the applicable equipment data collector andcontroller80, afirst wireless bridge76, asecond wireless bridge78, afirst antenna72, and asecond antenna74. Thefirst wireless bridge76 communicates instructions and data between the equipment data collector andcontroller80 and thefirst antenna72 while thesecond wireless bridge78 communicates instructions and data between the equipment data collector andcontroller80 and thesecond antenna74. Thefirst antenna72 communicates via thefirst wireless network36 transmitting the first set of status and operational data for processing and receiving data and instructions for controlling the equipment data collector andcontroller80. Thesecond antenna74 communicates via thesecond wireless network38 transmitting, concurrent with the same or substantially the same data transmitted via thefirst antenna72, the first set of status and operational data for processing, and receiving, concurrent with the same or substantially the same data and instructions received by thefirst antenna72, data and instructions for controlling the equipment data collector andcontroller80.
• The establishing of thefirst wireless network36 for monitoring and controlling the plurality of pieces of mobile mining equipment includes configuring a first set of wireless bridges comprising a plurality of the first wireless bridges76 to communicate according to a first frequency band.
• The establishing of thesecond wireless network38 for monitoring and controlling the plurality of pieces of mobile mining equipment concurrently with thefirst wireless network36 includes configuring a second set of wireless bridges comprising a plurality of second wireless bridges78 to communicate according to a second radio frequency band substantially different from the first radio frequency band. The second set of wireless bridges preferably communicate substantially the same data concurrently transmitted by corresponding ones of the first set of wireless bridges.
• Once the first andsecond wireless networks36 and38 have been established, a set of status and operational data are collected from each of the plurality of mobile mining equipment via the equipment data collector andcontroller80 positioned on each of the plurality of mobile mining equipment so as to form collected sets of status and operational data.
• Although in the first embodiment a single equipment data collector and controller is positioned on each piece of mobile mining equipment, it will be noted that alternatively two or more equipment data collectors and controllers may be positioned on each piece of mobile mining equipment that each communicate over the first andsecond wireless networks36 and38 via the first and second wireless bridges76 and78. In yet another variation, the twowireless bridges76 and78 may be replaced with a single wireless bridge that is operative to communicate on both the first andsecond wireless networks36 and38 via one or more antennae.
• In the first embodiment shown inFIG. 1, theremote plant28 comprises a hostequipment control computer29 that is operative to communicate with the mobile mining equipment over thewireless connections32 and34 via themobile slurry facility14, and is operative to control at least a set of features on the mobilemining process train50. The hostequipment control computer29 includes an equipment monitoring and control program stored on a computer-readable media and adapted to instruct the hostequipment control computer29 to perform the operations described below for the hostequipment control computer29. The computer-readable media may be of one or more types, including volatile memory such as Random Access Memory (RAM), and non-volatile memory, such as a hard disk or Read Only Memory (ROM).
• The collected sets of status and operational data from the first and second wireless bridges76 and78 positioned on the plurality of mobile mining equipment are transmitted via the first andsecond wireless networks36 and38 to the hostequipment control computer29.
• The hostequipment control computer29 is programmed to monitor for and process status and operational data specific to each of the pieces of equipment in the mobilemining process train50. The status and operational data is received via both the first and second wireless bridges76 and78 (FIG. 3) positioned on themobile slurry facility14 over thewireless connections32 and34. The status and operational data may include control data and run status data for each of the mobile mining equipment in the mobilemining process train50. At least part of each set of status and operational data is provided by the hostequipment control computer29 for display on a user interface displayed on a display device connected to the hostequipment control computer29 or a remote computer in communication with the host equipment control computer.
• Thus, the hostequipment control computer29 is operatively configured for processing at least part of the collected sets of status and operational data received from the first and second wireless bridges76 and78 and their associatedantennae72 and74 (seeFIG. 3) via the first andsecond wireless networks36 and38.
• The method of monitoring and controlling a plurality of mobile mining equipment including the establishing of the first andsecond wireless networks36 and38, the collecting and transmitting of the status and operational data, and subsequent process and display of the data is shown generally at100 inFIG. 4.
• The hostequipment control computer29 is preferably programmed to permit a user to control at least one piece of the mobile mining equipment of the mobilemining process train50 via the hostequipment control computer29 or a remote computer such as the wireless personal computing device90 (FIG. 8). This allows the user to control one or more features of one or more of the pieces of mobile mining equipment including themobile slurry facility14 andmobile sizer20. In another variation, the hostequipment control computer29 is preferably programmed to control and operate, in addition or in the alternative, themobile shovel22 or other pieces of mobile mining equipment.
• In another variation, the hostequipment control computer29 may be configured for providing at least part of the collected sets of status and operational data for display on a user interface of a field operator's personal computing device operative to remotely monitor and control at least a portion of the features of the plurality of mobile mining equipment. In yet another variation, the hostequipment control computer29 may be positioned on one of the pieces of mobile mining equipment, for example on themobile slurry facility14. Having the hostequipment control computer29 located on themobile slurry facility14 or another piece of mobile mining equipment allows for local control and operation of the mobile mining equipment even if the connection to theremote plant28 is lost. Local control and operation via the hostequipment control computer29 can enable a user such as an operator or controller to have improved visibility of the mobile equipment while operating same via the hostequipment control computer29 through thewireless networks36 and/or38. In yet another variation, the hostequipment control computer29 is a personal computing device, such as a wireless laptop computer.
• It will be noted that thewireless connections32 and34 and thewireless networks36 and38 provide for the same or substantially the same data to be transmitted and received over a plurality of connections, which provides for the ability of thesystem10 to remain operational so long as at least one of thewireless connections32 and34 and at least one of thewireless networks36 and38 are operational.
• In order to monitor for and respond to interruptions in communications over thesystem10, the hostequipment control computer29 is programmed to generate and provide a network activity alert signal to the user interface, if one of the first andsecond wireless networks36 and38 is interrupted including if communication is lost with any wireless bridge within one of the first andsecond wireless networks36 and38 for at least a predetermined time limit. In the first embodiment the predetermined time limit is set at 10 seconds, although other longer or shorter time limits may be used to meet the desired sensitivity of the system. For example, the predetermined time limit may be anywhere from about 600 milliseconds to about 10 seconds or more, depending on the distance between pieces of the mobile mining equipment. For shorter distances, such as when pieces of mobile mining equipment are about 300 to about 900 meters apart, the predetermined time limit may be about 600 milliseconds to about 1.5 seconds. For situations when pieces of mobile mining equipment or other equipment in thesystem10 are spaced apart at least about 1 km or more, the predetermined time limit is preferably no less than about 2 or 2.5 seconds, so as to provide time for round trip communications to occur with some lag without triggering a network activity alert signal warning of a possible loss of communication. In environments where more adaptability to potential, short interruptions may occur (such as due to intervening vehicles temporarily blocking a signal), a higher predetermined time limit is preferred, such as no less than about 3 seconds or more preferably yet about 4 seconds. This adds some further slack without triggering a network activity alert signal, and thereby adds further capacity for the networks to operate in the presence of minor lag, for instance where distances between points of communication extend to about 1 km or more.
• The hostequipment control computer29 is also programmed to generate and provide an equipment failure alert signal for further processing or for display on the user interface, if the run status data received for any piece of mobile mining equipment in the mobilemining process train50 indicates that the corresponding piece of mobile mining equipment has a failure falling within a predetermined class of critical failures. Preferably, the equipment failure alert signal identifies the corresponding piece of mobile mining equipment that has failed.
• In response to the equipment failure alert signal, the hostequipment control computer29 is preferably programmed to initiate a first type of shutdown of at least the portion of the plurality of mobile mining equipment in the mobile mining process train50 affected by the equipment failure. In this case, the mobile mining equipment affected by the equipment failure is or are preferably identified by the equipment failure alert signal. The first type of shutdown is preferably adapted to occur according to a first predetermined shutdown sequence adapted to at least the portion of the plurality of mobile mining equipment identified by the equipment failure alert signal as having the equipment failure. The predetermined shutdown sequence may also be adapted to other mobile mining equipment affected by an interruption in the operation of the mobile mining equipment having the equipment failure. In yet another arrangement, when the equipment failure alert signal identifies a critical equipment failure, the first type of shutdown is adapted to shut down all or substantially all of the operations of the mobilemining process train50.
• The hostequipment control computer29 preferably monitors, according to a predetermined verification schedule, the operability of each of the first andsecond wireless networks36 and38 by transmitting, via themobile slurry facility14, unique device identifiers to each of the first and second wireless bridges76 and78 positioned on each piece of mobile mining equipment in the mobilemining process train50. For each unique device identifier transmitted, the hostequipment control computer29 is instructed to monitor for receipt, via the corresponding wireless bridge positioned on themobile slurry facility14, of a receipt confirmation signal in less than the predetermined time limit from the corresponding wireless bridge (and associated antenna) of the corresponding piece of equipment in the mobilemining process train50.
• In addition, two or more of the equipment data collectors and controllers or the corresponding wireless communication equipment (e.g. corresponding wireless bridges and antennae), may be adapted, over the predetermined verification schedule, to transmit to and wait for confirmed receipt from each other heartbeat signals containing a unique identifier associated with the particular target recipient device. Failure to receive a confirmed receipt in the form of a return signal within the first predetermined time limit, or optionally within a second predetermined time limit different from the first predetermined time limit, results in detection of an interruption, which is then sent to the hostequipment control computer29. In one variation, this approach may be used to have any piece of mobile mining equipment transmit heartbeat signals and other signals to all other pieces of mobile mining equipment in the mobile mining process train50 that have an interlock relationship with the piece of mobile mining equipment transmitting the heartbeat signals or other signals.
• If either or both of the first andsecond wireless networks36 and38 are concurrently interrupted for at least the predetermined time limit, a network failure alert signal is provided by the hostequipment control computer29 to the applicable user interface. For instance, the network failure alert signal will be sent to the user interface if communications are lost with at least one wireless bridge in either or both each of the first andsecond wireless networks36 and38 for at least the predetermined time limit.
• The network failure alert signal preferably indicates which wireless bridges have lost communication. If the hostequipment control computer29 identifies a failure of both the first andsecond wireless networks36 and38, or at least one wireless connection in each of the first andsecond wireless networks36 and38, then the hostequipment control computer29 initiates a second type of shutdown of at least the portion of the mobile mining process train50 affected by the applicable failure. The second type of shutdown is preferably adapted to occur according to a second predetermined shutdown sequence at least adapted to or for the portion of the mobile mining process train50 affected by the failure of the first andsecond wireless networks36 and38. In yet a more preferable arrangement, the second type of shutdown is adapted to shut down all or substantially all of the operations of the mobilemining process train50.
• In the first embodiment shown inFIG. 1, the equipment data collector andcontroller40 positioned on themobile slurry facility14 is operative to receive status and operational data concurrently over both thefirst wireless network36 and thesecond wireless network38 from each of the other pieces of mobile mining equipment in the mobilemining process train50. In this embodiment, the equipment data collector andcontroller40 positioned on themobile slurry facility14 can be adapted to monitor, via both the first andsecond wireless networks36 and38, a first set of operating conditions associated with themobile mining conveyor16. The equipment and data collector andcontroller40 is programmed to commence a shutdown sequence for themobile slurry facility14 if, as one of the first operating conditions, an error condition is detected in association with themobile mining conveyor16 indicating at least one of: a failure in the operation of themobile mining conveyor16, an emergency shutdown of themobile mining conveyor16, a fire alarm associated with themobile mining conveyor16, a communication failure with themobile mining conveyor16, or a misalignment of themobile mining conveyor16 in association with the mobile slurry facility beyond a predetermined set of alignment parameters.
• The equipment data collector andcontroller40 can also be adapted to monitor, via both the first andsecond wireless networks36 and38, a second set of operating conditions associated one or more of themobile sizer20, themobile shovel22 or the hydro-transport booster pump house (HTBPH)24. In this instance, the equipment and data collector andcontroller40 can be configured to commence a shutdown sequence for themobile slurry facility14 if, as one of the second operating conditions, an error condition is detected in association with one or more of themobile sizer20, themobile shovel22 or the hydro-transport booster pump house (HTBPH)24 indicating a failure in downstream pumps associated with theHTBPH24 or a communication failure with one or more of themobile sizer20, themobile shovel22 or theHTBPH24.
• The equipment data collector andcontroller42 positioned on themobile mining conveyor16 can be adapted to monitor, via both the first andsecond wireless networks36 and38, a third set of operating conditions associated with the mobilemining conveyor hopper18. In this instance, the equipment and data collector andcontroller42 can be configured to commence a shutdown sequence for themobile mining conveyor16 if, as one of the third set of operating conditions, an error condition is detected in association with the mobilemining conveyor hopper18 indicating a communication failure with the mobilemining conveyor hopper18.
• The equipment data collector andcontroller42 can also be adapted to monitor, via both the first andsecond wireless networks36 and38, a fourth set of operating conditions associated with themobile slurry facility14. In this instance, the equipment and data collector andcontroller42 can be configured to commence a shutdown sequence for themobile mining conveyor16 if, as one of the fourth operating conditions, an error condition is detected in association with themobile slurry facility14 indicating at least one of: a failure in the operation of themobile slurry facility14, an emergency shutdown of themobile slurry facility14, a fire alarm associated with themobile slurry facility14, or a communication failure with themobile slurry facility14.
• The equipment data collector andcontroller45 positioned on themobile sizer20 can be adapted to monitor, via both the first andsecond wireless networks36 and38, a fifth set of operating conditions associated with the mobilemining conveyor hopper18. In this instance, the equipment and data collector andcontroller45 can be configured to commence a shutdown sequence for themobile sizer20 if, as one of the fifth operating conditions, an error condition is detected in association with the mobilemining conveyor hopper18 indicating at least one of: a failure in the operation of the mobilemining conveyor hopper18, an emergency shutdown of the mobilemining conveyor hopper18, a fire alarm associated with the mobilemining conveyor hopper18, or a communication failure with the mobilemining conveyor hopper18.
• The equipment data collector andcontroller44 can also be adapted to monitor, via both the first andsecond wireless networks36 and38, a sixth set of operating conditions associated with themobile mining conveyor16. The equipment and data collector andcontroller44 will commence a shutdown sequence for themobile shovel22 if, as one of the sixth operating conditions, an error condition is detected in association with themobile mining conveyor16 indicating at least one of: a failure in the operation of themobile mining conveyor16, an emergency shutdown of themobile mining conveyor16, a fire alarm associated with themobile mining conveyor16, or a communication failure with themobile mining conveyor16.
• Referring toFIG. 5, there is shown asystem10A, which is an alternate embodiment of thesystem10 inFIG. 1, wherein athird wireless connection35 and athird wireless network39 are included. Thethird wireless connection35 provides an additional connection (in addition to first andsecond wireless connections32 and34) for communication between themobile slurry facility14 and thesubstation26. Thethird wireless network39 provides an additional network connection for communication between each of the pieces of mobile mining equipment of the mobilemining process train50. Each communication device within thethird wireless network39 operates at a radio frequency band different than that of the radio frequency bands of the first andsecond wireless networks36 and38. Thethird wireless connection35 also operates at the same radio frequency as thethird wireless network39.
• Thethird wireless connection35 and athird wireless network39 may be adapted to support the concurrent communication of the same or substantially the same data and instructions as that which is communicated overwireless connections32 and34 and overwireless networks36 and38. In this configuration, thethird wireless connection35 and athird wireless network39 provide a yet further level of reliability to the wireless communication of data and instructions between the various pieces of mobile mining equipment in the mobilemining process train50 and between themobile slurry facility14 and theremote plant28 viasubstation26.
• In another alternative, thethird wireless connection35 and athird wireless network39 may be adapted to support the concurrent communication of different data and instructions from that which is communicated concurrently overwireless connections32 and34 and overwireless networks36 and38. In this configuration thethird wireless connection35 and athird wireless network39 can be used to provide segmented communication of data and instructions associated with features of the mobile mining equipment not communicated overwireless connections32 and34 and overwireless networks36 and38. For example, thethird wireless connection35 and athird wireless network39 may be adapted to communicate data and instructions associated with non-critical features of the mobile mining process train50 (e.g. data and instructions that do not need to be monitored or controlled for emergency shutdown purposes, such as video data or routine maintenance information). Transferring communication of non-critical data and instructions to thethird wireless connection35 and athird wireless network39 allows one to minimize the risk of overloading critical communications transmitted concurrently over both thewireless connections32 and34 and overwireless networks36 and38.
• In one variation, thethird wireless network39 may be configured according to the same communications standard as thefirst wireless network36, but allocated a dedicated channel of the communications standard that is sufficiently different from other channels making up the communications standard so as to minimize the risk of interference between the first and third wireless networks. For example, where thefirst wireless network36 is configured for 802.11 g and thethird wireless network39 may also be configured for 802.11 g, provided thethird wireless network39 is allocated a select dedicated channel within 802.11 g different from the channels used by thefirst wireless network36 within the 802.11 g standard. In such an arrangement, the first wireless bridges forming part of thefirst wireless network26 are preferably configured to provide the select dedicated channel to thethird wireless network39. In one arrangement of this variation, each antenna used for thefirst wireless network36, when positioned on a piece of mobile mining equipment, is spaced apart at least about 2 meters from the antenna used for the third wireless network.
• Referring toFIGS. 5 and 6, a further variation (10B) ofsystem10A is provided involving another embodiment of athird wireless connection35 and athird wireless network39. InFIG. 6wireless connection61 is equivalent tothird wireless connection35 andwireless network63 is equivalent tothird wireless network39. In the variation shown inFIG. 6,wireless connection61 andwireless network63 operate on the same radio frequency band, which is sufficiently different from that of the radio frequency bands ofwireless connections32 and34 andwireless networks36 and38 so as not to interfere withwireless connections32 and34 andwireless networks36 and38. It should be noted that thewireless connection61 and thewireless network63 may operate on different radio frequency bands from each other if desired, provided they do not interfere with the communications overwireless connections32 and34 andwireless networks36 and38. In the embodiment shown inFIGS. 5 and 6 combined, each of themobile slurry facility14, themobile mining conveyor16, the mobilemining conveyor hopper18, themobile sizer20, and themobile shovel22 are fitted with one ormore cameras65. Video feed from thecameras65 is transmitted over thewireless network63 andwireless connection61 to theremote plant28 allowing a user to visually monitor each of the mobile mining equipment of the mobile mining process train50 as well as the surrounding operating conditions. The video feed may also be viewed at a facility or a computer not located within theremote plant28. For example, the video feed may be viewed on thepersonal computing device90 as shown in the embodiment ofFIG. 8.
• Referring toFIG. 7, asimplified system10C is shown, which is a variation of thesystem10 inFIG. 1. InFIG. 7, thesystem10C provides for communication between a minimum of two pieces of mobile mining equipment making up the mobile mining process train50 shown inFIG. 1. In this variation, for illustration purposes, the mobile mining equipment used are themobile slurry facility14 and themobile mining conveyor16, although other sets of mobile mining equipment may be selected for purposes of wireless communication. In this embodiment, themobile mining conveyor16 communicates with themobile slurry facility14 concurrently over both afourth wireless connection47 and afifth wireless connection48.Wireless connections47 and48 provide a point-to-point wireless connection between themobile mining conveyor16 andmobile slurry facility14. The radio frequency band ofwireless connection47 is different from the radio frequency band ofwireless connection48, so as to avoid interference between the two concurrently operating connections.
• Referring toFIG. 8, in another variation (10D) of thesystem10 inFIG. 1, apersonal computing device90, such as a personal laptop computer, may be provided in addition to or in substitution of the hostequipment control computer29. Thepersonal computing device90 is operative to communicate wirelessly with the mobile mining equipment of the mobilemining process train50 via the first andsecond networks36 and38. Thepersonal computing device90 also comprises an instance of the equipment monitoring and control program stored on a computer-readable media local to or in communication with thepersonal computing device90. In an alternative embodiment, thepersonal computing device90 may communicate with the mobile mining equipment indirectly via anothernetwork92 such as the Internet or an intranet with which a secure communication is established directly or indirectly, for instance via thesubstation26 or theremote plant28.
• In another variation, asystem10E is shown inFIG. 9, which corresponds to a variation of thesystem10 shown inFIG. 1, further adapted to cooperate with a plurality of mobile mining process trains. For instance, thesystem10E may be adapted to cooperate with both a first mobile mining process train50A over afirst wireless network36A and asecond wireless network38A, and with a second mobilemining process train50B over athird wireless network36B and afourth wireless network38B. In this variation, the second mobilemining process train50B is remote from the first mobilemining process train50A, and the second mobilemining process train50B includes a second plurality of mobile mining equipment. Thesystem10E can include a second plurality of equipment data collectors and controllers each positioned on a corresponding one of the second plurality of mobile mining equipment. Each of the second plurality of equipment data collectors and controllers is operative to collect a set of status and operational data from the corresponding one of the second plurality of mobile mining equipment, and is operative to control at least one feature of the corresponding one of the second plurality of mobile mining equipment. In addition, each of the second plurality of equipment data collectors and controllers is preferably in communication with a third wireless bridge and a fourth wireless bridge.

The third wireless bridges collectively form thethird wireless network36B and the fourth wireless bridges collectively form thefourth wireless network38B, in addition to thefirst wireless network36A and thesecond wireless network38A established for the first mobilemining process train50A as illustrated and described above in connection withFIG. 1.
• The data collector and controller positioned on the second mobile slurry facility is preferably further operative to receive status and operational data concurrently over both the third wireless network and the fourth wireless network from each of the other data collectors and controllers positioned on the other pieces of equipment in the second mobile mining process train.
• In this variation (10E) the equipment monitoring and control program preferably comprises computer-readable instructions adapted to instruct the host equipment control computer to:
• • (a) monitor for and process status and operational data specific to each of the pieces of equipment in the second mobile mining process train, received via both the third and fourth wireless bridges positioned on the second mobile slurry facility, including control data and run status data for each piece of equipment in the second mobile mining process train;
  • (b) provide at least part of each set of status and operational data received in association with the second mobile mining process train for display on the user interface displayed on the display device connected to at least one of the host equipment control computer and the remote computer in communication with the host equipment control computer;
  • (c) provide a second network activity alert signal to the user interface if one of the third and fourth wireless networks is interrupted including if communication is lost with any wireless bridge in one of the third and fourth wireless networks for at least the predetermined time limit; and
  • (d) provide a second equipment failure alert signal if the run status data received for any equipment in the second mobile mining process train indicates that the corresponding piece of equipment has a failure falling within the predetermined class of critical failures, wherein the equipment failure alert signal identifies the corresponding piece of equipment that has failed.
• In another variation, thesystem10 illustrated in connection withFIG. 1 or any of the variations thereof illustrated in connection with the other figures, can have the first andsecond wireless networks36 and38 adapted to support a mesh network. With a mesh network, communications between the hostequipment control computer29 or any one piece of mobile mining equipment and another piece of mobile mining equipment can be established either directly (where available) or indirectly via any one or more intermediate pieces of mobile mining equipment within communications range and capable of establishing an indirect communications link. For instance, in this variation, communications between the host equipment control computer and themobile sizer20 may be established either via themobile slurry facility14, directly or via the mobilemining conveyor hopper18, themobile mining conveyor16 and themobile slurry facility14. In another example, themobile slurry facility14 may communicate indirectly with the other pieces of mobile mining equipment, for instance, with the mobilemining conveyor hopper18 via themobile mining conveyor16. This added adaptability enables the first andsecond wireless networks36 and38 to be established and remain even more reliably available without any substantial interruption even in the presence of additional potential obstructions for direct communications or where two pieces of mobile mining equipment which are intended to communicate with each other are unable to directly communicate with each other because of the distance between them.

• In yet another variation, thesystem10 illustrated in connection withFIG. 1 can be adapted to collect and analyze data associated with one or more maintenance networks. For instance, thesystem10 can be adapted to collect and analyze data associated with one or more variable frequency drives (VFDs) used by one or more of the pieces of mobile mining equipment. For example, VFD data that can be collected by equipment data collectors and controllers positioned on corresponding pieces of mobile mining equipment include data relating to: current, torque, speed of operation, voltage, power factor, temperature and/or rectifier problems.
• In yet another variation, thesystem10 illustrated in connection withFIG. 1 can be adapted to operate using only thefirst wireless network36, in the absence of thesecond wireless network38. With a single wireless network, however, there is an increased risk of network failure, and in such an arrangement, if one node in the wireless network goes down, thesystem10 is adapted to shut down all or substantially all of the operations of the plurality of mobile mining equipment in the mobile mining process train. To reduce the risk of network failures when only the first wireless network is established, it is preferable to conduct site surveys to check for signal interfering objects or equipment with much greater frequency. In order to improve network reliability when only a single wireless network is used, it can be preferable to move from an unlicensed frequency such as 802.11 g, to a licensed frequency. This will provide a dedicated frequency or set of frequencies for the first wireless network in thesystem10. In another variation, a satellite may be dedicated to thesystem10 to avoid unexpected or uncontrollable downtime by the owner of the licensed frequency. In an alternative, hybrid arrangement, thefirst wireless network36 may be supplemented by a second cable network comprising a fiber optic cable network. In the case of mobile mining equipment, the fiber optic cable is preferably embedded through trailing cable (power cable) for the plurality of mobile mining equipment, so as to protect and organize the fiber optic cable.
